Car-Rep Copper Etch & Weld Through Primer Aerosol
CAR-REP Copper Etch & Weld Through Primer A professional-grade copper-based etch primer designed to protect metal surfaces while allowing clean, conductive weld-through performance. Ideal for automotive repairs, fabrication, and panel work where corrosion resistance and strong adhesion matter. What it does: This primer chemically etches into bare metal, creating a strong bonding surface while laying down a copper-rich coating that resists corrosion and allows electricity to pass through for welding. Perfect for: Bare steel, aluminium, and galvanised surfaces Panel repairs and replacements Areas that need to be welded after priming Rust prevention in hard-to-reach joins and seams How to use: Clean and degrease the surface thoroughly Lightly sand if required for better adhesion Shake can well (at least 2 minutes) Apply thin, even coats from 20–30cm away Allow to flash off before welding or top coating
